Comments: Location: Tall Tree Rd. Stream: Small pool at inlet; braids forming 125ft upstream. The tailcrest is formed by rocks with overgrown vegetation. No stream flow measurements due to narrow, braided channel reducing flow. Culvert: 1 overflow pipe. Outlet perched ~3'. Inlet pipe is a few inches above the substrate causing a pool and limited flow--potentially a barrier. Pipe condition=5. Not embedded.
